HYDROXY-SUBSTITUTED N-ALKOXY HINDERED AMINES AND COMPOSITIONS STABILIZED THEREWITH

摘要

Hindered amines substituted on the N-atom with a hydroxy-substituted alkoxy moiety, bridging 2 or more 2,2,6,6,-tetraalkylpiperidine moieties, are particularly effective in stabilizing organic polymer compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not otherwise attainable.
